SS		 281999-02-11 Hugo Tyson <hmt@cygnus.co.uk>
29
30 * exec.c (dispatch_instruction):
31 Correct the sense of the
32 if (!sparclite) {
33 sregs->trap = TRAP_UNIMP;
34 break;
35 }
36 clause that has been pasted around: it's correct in the SCAN and
37 DIVScc (divide step) cases (where it was probably originally
38 written?), but reversed in the SDIV, SDIVcc, UDIV, UDIVcc cases
39 ie. instructions only in the SPARC V8 or SPARClite 86x
40 architectures. It was also present when not required for SMUL,
41 SMULcc, UMUL, UMULcc instructions that are present in all
42 architectures.
43
441999-01-25 Hugo Tyson <hmt@cygnus.co.uk>
45
46 * interf.c (run_sim): Fix a bug in the main loop's handling of
47 annulled delay slot instructions. There is precedent for this
48 change; the _other_ main loop in sis.c gets it right according to
49 my reading of the code.
50
51 The bug is: if an interrupt happens when the next instruction
52 (at sregs->pc) is annulled, the trap is taken (by execute_trap())
53 with the current values of PC and NPC, so when the trap returns,
54 the annulled instruction is indeed executed. Another giveaway is
55 that the annul flag is cleared in execute_trap(): the information
56 is demonstrably discarded.
57
58 The solution is: perform annulling before looking for traps, in
59 fact it's neater to do annulling, see if there's an interrupt and
60 if not, do the instruction, then handle traps be they generated by
61 interrupts pending or by the instruction we might just have done.
62 That's what the sis.c one does.
63
641999-01-20 Hugo Tyson <hmt@cygnus.co.uk>
65
66 * sis.h: Add asr17 register for support of SparcLITE (at least the
67 Hitachi ones I find before me)
68
69 * exec.c (dispatch_instruction): Case WRY: Allow write of asr17 if
70 sparclite. Other ASR numbers than 17 or 0 (Y) trap out.
71 Case RDY: Allow read of asr17 if sparclite. Other ASRs ditto.
72 (execute_trap): Do single-vector-trapping if asr17 bit 0 is set.
73 (init_regs): Initialize y and asr17.
74 NB: In instruction-set space, the Y register is asr0; the
75 instructions have different names for human reasons only.
76
77 * sis.c:
78 * interf.c: Set boolean mode variable dumbio if invoked with
79 argument "-dumbio" and mention it of verbose.
80 * erc32.c: if "dumbio" is set, do not assume that there is a
81 terminal type device attached to stdin/stdout. Do not set
82 buffering or mess with tcsetattr or do any read operations in
83 order to make UART interrupts; not input data is supported.
84 This is necessary to allow the sim to be used within the eCos
85 testing infrastructure where stdin/stdout are pipes to a TCL
86 program; the sim hangs otherwise.
87
88Thu Jul 23 07:17:03 1998 Mark Alexander <marka@cygnus.com>
89
90 * exec.c (dispatch_instruction): Add SPARClite 'scan' instruction.

105
106Tue Jun 2 15:20:35 1998 Mark Alexander <marka@cygnus.com>
107
108 * interf.c (sim_open): Use revamped memory_read, which makes
109 byte-swapping unnecessary. Add -sparclite-board option for
110 emulating RAM found on typical SPARClite boards. Print
111 error message for unrecognized option.
112 * erc32.c: Change RAM address and size from constants to variables,
113 to allow emulation of SPARClite board RAM.
114 (fetch_bytes, store_bytes): New helper functions for revamped
115 mememory_read and memory_write.
116 (memory_read, memory_write): Rewrite to store bytes in target
117 byte order instead of storing words in host byte order; this
118 greatly simplifies support of little-endian programs.

120 (sis_memory_write, sis_memory_read): Store words in target
121 byte order instead of host byte order.

128 makes byte-swapping and double-word fetching unnecessary.
129 * func.c (sparclite_board): Declare new variable.

131 (bfd_load): Recognize little-endian SPARClite as having
132 little-endian data.

451 * (sim_stop_reason): Define SIGTRAP if _WIN32.
452 * sis.h: Include ansidecl.h and remote-sim.h.
453
454Wed Jul 3 16:05:23 1996 Stu Grossman (grossman@critters.cygnus.com)
455
456 * erc32.c (mec_reset mec_read mec_write memory_read memory_write),
457 sis.h: Get rid of all uses of long long's.
458 * (close_port read_uart write_uart uarta_tx): Don't seg fault
459 when can't open pty's.
460 * exec.c: Add two new instructions: smul, and divscc.
461 * interf.c (flush_windows): New routine to flush the register
462 windows out to the stack just before returning to GDB. Makes
463 backtraces work much better.
464
465Wed Jun 26 12:19:11 1996 Jason Molenda (crash@godzilla.cygnus.co.jp)
466
467 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
468 INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
469 (docdir, oldincludedir): Removed.
470 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
471 (AC_PROG_INSTALL): Added.
472 * configure: Rebuilt.
473
474Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
475
476 * configure.in: Call AC_PROG_CC before running configure.host.
477 * configure: Rebuild with autoconf 2.10.
478
479Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
480
481 * Makefile.in (install): Don't check to see if tooldir exists.
482 Make $(tooldir) and $(tooldir)/bin.
483
484Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
485
486 * Makefile.in (end.h): Use explicit ./ when running end.
487
488Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
489
490 * func.c(bfd_load): Don't try to print the filename if the pfbd is
491 NULL.
492 * interf.c(sim_load): Pass the whole string, not just the first
493 byte.
494
495Version 2.1 26-02-96
496--------------------
497
498* Fixed bug in "go" command.
499
500version 2.0 05-02-96
501--------------------
502
503* Fixed bug in interrupt force register (erc32.c).
504
505* Change file load function to use bfd_openr.
506
507* SIS should now be endian independent.
508
509version 1.8 24-11-95
510--------------------
511
512* Fixed FPU timing - some sequences of FPU instructions did not calculate
513 the resource dependencies right.
514
515* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
516 but no FPU trap is generated.
517
518version 1.7.1 31-10-95
519--------------------
520
521* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
522 the FPU stays in execute mode.
523
524* Corrected JMPL and RETT timing (these instructions takes two cycles).
525
526
527version 1.7 25-10-95
528--------------------
529
530* Interrupt during annuled instruction corrupted return address - fixed.
531
532
533version 1.6.2 25-10-95
534--------------------
535
536* Added -DFAST_UART to Makefile
537
538
539version 1.6.1 24-10-95
540--------------------
541
542* Fixed bug in STDFQ which caused bus error
543
544
545version 1.6 02-10-95
546--------------------
547
548* Modified srt0.s to include code that initiates registers in IU and FPU
549 and initializes the data segment. The simulator 'load' command does not
550 longer initialize the data segment!
551
552* Corrected MEC timer operation; scalers now divide the frequency by
553 (scaler_value + 1).
554
555* MEC breakpoints are not checked during store operation
556
557
558version 1.5 14-09-95
559--------------------
560
561* Fixed some bugs in the cycle counting for IU & FPU instructions.
562
563* Fixed bug that allowed an annuled instruction to cause memory exception.
564
565* The *ws parameter in mem.c should now contain the number of waitstates
566 required by the memory access (was total number of cycles).
567
568* The supplied srt0.s now clears the BSS (thanks Joel).
569
570version 1.4 22-08-95
571--------------------
572
573* Added a '-g' switch to enable/disable the GNU readline(), which cause
574some problems on solaris 2.x machines.
575
576* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
577may suffer a bit ...
578
579NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
580
581version 1.3 26-07-95
582--------------------
583
584* Fixed bug in mulscc instruction (how could that ever have worked?)
585
586* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
587
588version 1.2 13-07-95
589--------------------
590
591* Fixed bug in interrupt handling (wrong interrupt selected when more that
592one interrupt pending)
593
594* Fixed updating of condition codes during logical instructions (carry and
595overflow were not reset)
596
597* Fixed bug in WRTBR (tt field was wrongly over-written)
598
599version 1.1 07-07-95
600--------------------
601
602* Fixed several bugs in the interrupt handler and callback routines.
